Yes they would be considered “super-ippons”, and would score ippon in competition.

Edit: Arrived home now after judo training – searched online for the term and appears in a few refereeing articles:

>They did make an exception for something that they’re calling a “Super Ippon”: this is basically where one guy throws the Bejesus out of the other one but the thrown guy may land on his side instead of on his back. If it’s super fast, super hard and with super control, they will make an exception on the “largely on the back” rule

Homeboy has his undergrasp lapel on every single throw which is what needs to be accounted for. Not saying it’s an easy task bc he also has great control of uke’s sleeve. Japanese grip fighting is very good and they know how to get the grip they like. I am just starting to study this art further as a shodan
